Seasonal Micro- and Macro-Mineral Profile and Proximate Composition of Oyster (Ostrea edulis) Analyzed by ICP-MS

Abstract

Oysters (Ostrea edulis) were investigated for micro-macro-mineral content and proximate composition throughout the year. Mercury, lead and aluminium were found to be below the legislative limits, while zinc was over throughout the year. Cadmium and copper were over legislative limits in winter. While the highest Na, Mg and Ca values were found in autumn, the highest K and P contents were found in spring. Ranges of moisture, protein, fat and ash contents were 71.06-80.65, 6.85-10.30, 1.47-5.51 and 3.42-9.45 g/100 g, respectively. While the highest protein, fat, ash values were found in spring, the highest moisture contents were found in autumn.
